[flutter]加载网络图片报错: Bad state: In

flutter报错: Bad state: Insecure HTTP is not allowed by platform:

1、新建network_security_config.xml

<?xml version="1.0" encoding="utf-8"?>

<network_security_config>
    <base-config cleartextTrafficPermitted="true">
        <trust-anchors>
            <certificates src="system" />
        </trust-anchors>
    </base-config>
</network_security_config>

2、AndroidManifest.xml application标签内添加 android:networkSecurityConfig="@xml/network_security_config"

<application
        android:networkSecurityConfig="@xml/network_security_config"
        android:label="holler_flutter"
        android:icon="@mipmap/ic_launcher">

3.然Stop项目，重新Run运行即可。
